I got my DS3 Tank in the mail today, and so far I love it! At 4 volts, it really gives my juice awesome flavor! I hope you get replacement bottom clearomizers in for it, because if my first impressions are any indication, I'm likely to use this tank quite a bit.
Update: Ok, it's been several hours and some problems have developed - The tank is leaking from the center post - I lost 2ml of juice before I noticed it all over my battery and desk, and I am getting a LOT of gurgling from the tank. Just trying to use up the juice left in it right now so that I can take it apart, and try to identify the problem. Any suggestions???
